OSSTMM

OSSTMM (Open Source Security Test Methodology Manual) is a manual on security testing and analysis.

The OSSTMM test cases are divided into five channels (sections) which collectively test: information and data controls, personnel security awareness levels, fraud and social engineering control levels, computer and telecommunications networks.

OSSTMM focuses on the technical details of exactly which items need to be tested, what to do before, during, and after a security test, and how to measure the results. New tests for international best practices, laws, regulations, and ethical concerns are regularly added and updated.

More information on OSSTMM can be found on the official OSSTMM website.
